Embodiment Construction

[0012] The invention provides a heating element. Further description will be given below in conjunction with the accompanying drawings. exist figure 1 In the schematic diagram of the heating element structure shown, the plate core 3 in the middle of the heating element is processed into an alloy wire mesh heating element by imported nickel-chromium alloy wire, and is covered with a high-temperature-resistant inorganic heat-conducting and insulating ceramic material (mixed firing of silicon carbide and kaolin) on the outside. Composite ceramics made of composite ceramics); the two sides of the core 3 are covered with refractory magnesium oxide powder and other metal oxides, and the high-strength heating element skeleton 2 is composed of carbon products such as graphite and high-temperature-resistant, heat-conducting and insulating inorganic binders. The outer surface of the heating element skeleton 2 is closely attached to the stainless steel metal grid, and the outer surface ...

Abstract

The invention discloses a heating element, which belongs to range of heating components. The middle of the heating element is a plate core formed by covering high-temperature resistant heat-conduction insulating ceramic materials onto high-quality alloy wire heater; both side surface of the plate core are provided with a heating element skeleton which is composed of metal oxide, carbon materials and high-temperature resistant heat-conduction insulating inorganic binder, the outer side surface of the heating element skeleton is provided with stainless steel metal meshes in a clinging way, the outer side surface of the stainless steel metal meshes is provided with nano far-infrared material and high-temperature resistant moisture-proof covering. The advantages of the invention are as follows: the heater provided by the invention has small deformation, long the service life, hard brittleness, no power recession; the heat of the heating core plate not only can be fully discharged, but also can overcome the defect of degradation of electrical insulation performance during using due to moisture absorption when the electric heater is not used; the thermal efficiency can reach up to 99% or more, the radiation area is large, the radiation cooling is strong, and the comfort is good.

Description

technical field [0001] The invention belongs to the scope of heating components, in particular to a heating element. Background technique [0002] Most of the traditional electric heating elements are nickel-chromium wire, iron-chromium-aluminum wire, tungsten wire or constantan wire. Most of these materials are bare wires, which are easy to oxidize in the air, making the heating element thermally deformed, brittle, generating power decline, heating efficiency is affected, and the service life is short. Contents of the invention [0003] The purpose of the present invention is to provide a heating element, which is characterized in that the middle of the heating element is a plate core composed of a high-temperature resistant inorganic heat-conducting insulating ceramic material coated alloy wire mesh heating element; the two sides of the plate core are coated with metal oxide, The skeleton of the heating element composed of carbon materials and high-temperature-resistant...
